How Louisville Used GPS to Improve Residents' Asthma

Louisville, Kentucky has some of the worst air pollution in the U.S., which is particularly bad news for the 85,000 people in surrounding Jefferson County (about 11 percent of the population [PDF]) who have been diagnosed with asthma.

The air quality situation in Louisville won’t be changing anytime soon, but a new study with sensor-equipped inhalers shows that technology can help people with asthma cope, as CityLab reports. The two-year AIR Louisville project involved the Louisville government, the Institute for Healthy Air Water and Soil, and a respiratory health startup called Propeller, which makes sensors for inhalers that can track location and measure air pollutants, humidity levels, and temperature.

Propeller's inhaler-mounted sensors allowed the researchers to monitor the relationship between asthma attacks and environmental factors and provided new insight on how air quality can change from neighborhood to neighborhood. The sensors—which are already used by doctors, but have never been deployed citywide before—can measure levels of nitrogen oxide, sulfur, ozone, particulate matter, and pollen in the air, plus track location, temperature, and humidity, all of which can impact the risk of asthma attacks. The sensors send Propeller data on when, where, and how many "puffs" patients take to track how often people are resorting to emergency medication.

Propeller sent out app notifications to warn the Louisville program participants of greater risk of an asthma attack on bad air quality days, and showed them where and when the most asthma attacks happened around the city.

The Propeller program illuminated just how much more asthma-triggering pollution the city’s west side (predominantly home to poor, African-American residents) faces compared to other neighborhoods. The data also showed that ozone provoked an uptick in asthma attacks throughout the city, namely along highways. The study may end up influencing air quality regulations, since the researchers found that air pollutants became problematic for asthma sufferers even under the legal levels.

The program had huge short-term benefits, too, beyond collecting research for city policies. By the time it ended in late June, the study clearly had a significant impact on the nearly 1200 people with asthma and chronic obstructive pulmonary disease (COPD) who took part. The asthma group showed a decline in average inhaler use after a year. There was an 82 percent decline in people's weekly average uses of rescue inhalers at the 12-month follow-up, and the participants had twice the number of symptom-free days. The majority of participants said they understand their asthma "very well" or "well," can better control it, and feel confident about avoiding a bad asthma attack.

Now that the program is over, the institutions involved are still working to launch new policies based on the results, like creating citywide asthma alerts and planting more trees.

Queen's 'Bohemian Rhapsody' Is Officially the Most Streamed Song of the 20th Century

Queen's "Bohemian Rhapsody" was a massive hit when it was released in 1975. After spending nine weeks at the top of the UK charts (it only broke the top 10 on the U.S. charts), it went on to become the third bestselling UK single of all time. Even as the way people listen to music has changed, the mock opera's popularity hasn't wavered. Now, "Bohemian Rhapsody" is officially the most streamed song recorded in the 20th century, Entertainment Weekly reports.

Queen's song has been streamed by listeners a staggering 1.5 billion times, putting it ahead of classic rock tracks like "Smells Like Teen Spirit" by Nirvana and "Sweet Child O' Mine" by Guns N' Roses. But when looking at overall streaming numbers, contemporary tracks still dominate. Combined, the original version of "Despacito" and the remix garnered 4.6 billion plays in just six months last year.

This latest milestone for "Bohemian Rhapsody" is even more satisfying when you know the song's backstory. The long play time and unconventional, operatic style made some music industry insiders—including the band's manager and Elton John—skeptical of its marketability. When the song debuted on the radio, listeners calling in to demand more quickly proved them wrong.

The track likely got a boost in popularity recently with help from the Freddie Mercury biopic that shares its name. Bohemian Rhapsody, starring Rami Malek, hit theaters in early November and is now officially the second-highest grossing musical biopic of all time, just behind 2015's Straight Outta Compton. But it's not the first time a hit movie has led to renewed interest in the song: the tune saw a similar spike in sales—and it reentered the charts and hit No. 2—when it played an integral part in the hit 1992 comedy Wayne's World.

The Pigzbe Wallet Teaches Kids How to Budget and Save Money

Fiscal responsibility isn’t the most exciting topic in the world, especially when you’re in elementary school. But, as Fast Company reports, Primo Toys is hoping to make the concept more child-friendly. The company’s new Pigzbe wallet works like a digital piggy bank to teach kids age 6 and older how to earn, budget, and save money by managing the cryptocurrency they receive from their parents.

Pigzbe connects to a smartphone app, which parents can use to set chores and tasks for their kids to complete, such as making their bed or washing the dishes. They can set a schedule for these chores (every Tuesday, for example) as well as monetary rewards in the form of Wollo, a “family-friendly” cryptocurrency developed by Primo Toys.

Tasks will be sent directly to the Pigzbe device, and once they have been completed, kids will receive their hard-earned Wollo tokens. The Pigzbe app helps kids visualize their earnings and how much they’ll need to save to get the items they want. "It’s a design that feels childlike, sure, but in a fun, self-aware way, almost like a Tamagotchi," Fast Company notes.

Although Wollo isn’t technically “real money,” the tokens can be used to purchase toys and other items from Pigzbe’s app. Parents can also order a specialized Visa card that will let them buy items using Wollo. Other family members can also send gifts and allowances to any Pigzbe user, no matter their geographic location.

The goal is to teach kids about financial responsibility at an early age, when they’re just beginning to form habits that will stick with them well into adulthood. “We believe that financially curious children become financially literate adults, and we designed Pigzbe to achieve just that,” Primo Toys, the maker of the Pigzbe wallet, writes in its Kickstarter campaign. The product has already exceeded its $50,000 fundraising goal, with more than 550 backers on board.

Backers who pledge $79 or more before the campaign ends on January 25, 2019 will receive the Pigzbe wallet at a 40 percent discount.
